What membrane surrounds lungs heart and organs in the abdomen?

The membrane that surrounds the lungs is called the pleura, which consists of two layers: the visceral pleura (lining the lungs) and the parietal pleura (lining the chest wall). The heart is encased in a membrane known as the pericardium, which also has two layers: the visceral pericardium (attached to the heart) and the parietal pericardium (forming the outer layer). The organs in the abdomen are surrounded by the peritoneum, a membrane that also has visceral and parietal layers, providing support and protecting the abdominal organs.
